CROSS REFERENCE TO RELATED APPLICATION

The present application is related to and claims priority to U.S. Provisional Patent Application No. 62/481,308 filed 2017 Apr. 4, which is incorporated by reference herein in its entirety.

BACKGROUND OF THE INVENTION

The following includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art nor material to the presently described or claimed inventions, nor that any publication or document that is specifically or implicitly referenced is prior art.

1. Field of the Invention

The present invention relates generally to the field of shelters suspended from diverse support means and more specifically relates to a frameless shelter suspended from an overhead structure.

2. Description of Related Art

Keeping dry outdoors during inclement weather can be difficult, especially for those who are camping, hiking, and the like. When setting up a rain fly, people are forced to look for trees. This process can be time-consuming and may be impossible in some remote locations. It can start raining quickly, and swiftly setting up shelter is of paramount importance. Further, most tarps and shelters take up excessive amounts of storage space and may be heavy to carry. Moreover, customary tarp shelters require one or more rigid poles or multiple overhead support points. A system allowing for the erection of shelter without need for the rigid poles or multiple overhead support points would benefit many.

Prior attempts have been made to overcome the above-noted limitations. For example, U.S. Pat. No. 6,338,356 to Wallenstatter relates to a portable tent. The described portable tent includes a portable tent having an interior, mesh-like netting portion, and an outer, waterproof canvas covering which may double as a poncho. The tent requires no assembly components other than stakes to affix the bottom of the tent to the ground and a top securing plate which is removably secured to a support object such as a tree limb. The top metal plate has a plurality of fastening rings on its upper and lower sides and is tied to the object situated substantially above the place where the tent is to be erected. A unique flexible support ring is woven into the fabric of the interior netting portion to support the sides of the tent structure. An object such as a cellular telephone or a flashlight may be suspended from an interior suspension ring situated on the bottom side of the plate via twine or string to allow the occupant to conveniently protect valuable or electronic accessories or to provide hands-free illumination from above during tent assembly. The outer, canvas covering conveniently doubles as a waterproof poncho by simply disengaging it from its support fasteners and the support plate. The entire tent, including both inner and outer enclosures may be folded neatly into a carrying case thereby allowing an entire waterproof tent structure to be transported easily and conveniently.

DETAILED DESCRIPTION

As discussed above, embodiments of the present disclosure relate to a shelter that may be suspended from diverse support means and more particularly to an outdoor shelter system and method as used to improve the art of frameless shelters that may be suspended from overhead structures.

Generally, the present system provides outdoor enthusiasts with a reliable canopy capable of being set up at any location outdoors. As designed, the system virtually eliminates the need to locate trees and other wildlife for ample protection from the weather. It utilizes a nylon-based rope in order to tie down all corners of the canopy, thus allowing the device to be staked securely into the ground. The device deploys quickly and easily without the need for excessive amounts of tools. The present system allows users to fold/roll up the canopy and all components for storage in a travel bag, offering lightweight transportation while camping, hiking, fishing, and the like. The frameless outdoor shelter system is a suspension canopy capable of being suspended from a single tree limb. The system is intended to provide ample shelter and be deployed in a swift manner. The canopy is comprised of a silnylon material and can be folded compactly for storage in a backpack or other storage pack. The canopy can use a bridal loop in the center to hoist the shelter up onto the tree limb. Users can throw a line over any tree branch while maintaining control over both sides of the rope. The thrown side is hooked to the bridal loop in the center of the canopy. Users can pull the other side of the rope, lifting the canopy to a desired height. Users can then apply four or more reinforced metal loops to stake down the canopy. The long side of the rope can be tied off away from the canopy to the tree or another heavy object. The frameless outdoor shelter system can be constructed using durable, weather resistant materials. The canopy may be available in various sizes; however, a standard version may measure approximately 10 feet in length and 10 feet in width. Exact size, measurement, construction, and design specifications may vary upon manufacturing. For example, in another embodiment, the canopy may include an aperture in a center thereof, and a hood. In this embodiment, the bridal loop may be located on top of the hood. The location of the bridal loop in various embodiments may provide a same tension point.

Implementations of the system may include a long oval with reinforced stitching along the outside seams with a patch stitching bridal loop in the center of the canopy for the suspension-based system. The suspension line may be thrown over a sturdy branch of any one tree while having control over both sides of the rope. The thrown side of the rope may be hooked to the bridal loop in the center of the system while pulling the other side of the rope to lift the canopy. After a selected canopy height is achieved, the four or more reinforced stitched in loops may be used to stake down the canopy. The long side of the rope may be tied off away from canopy to the tree or a heavy source.

In summary, the system provides a suspension-type canopy, which requires one tree and no poles and is extremely convenient to carry in a backpack. The frameless outdoor shelter system may be constructed out of silnylon, making the apparatus compactable to the size of the smallest pocket of most hiking packs. The frameless outdoor shelter system was made to keep people dry, and out of the elements as fast as possible when needed the most. There is no need to carry a large tent bag or tent poles. The system can cover a hammock on a hot summer day or may extend over a fishing spot while it rains. Staying dry is paramount during outdoors activities. The system is easily packable, light weight, and is an easily deployable way to keep users sheltered from the elements.

Referring now more specifically to the drawings by numerals of reference, there is shown in FIGS. 1-7, various views of a frameless outdoor shelter system 100.
